Automation and Controls Engineer

Valar Atomics is seeking Automation and Controls Engineers to help develop, configure, test, and commission the control system software for our reactor and nuclear fuel manufacturing facilities. Working under the technical direction of senior and staff engineers, you will contribute across the controls software domain PLC programming, SCADA and HMI development, batch control, alarm configuration, historian work, and control system testing, with steadily increasing independence and ownership. This is an early-career position built for growth: you will write real application code that runs a real plant, spend time at panels and in the field during loop checks and commissioning, have your work reviewed and tested by experienced engineers, and learn nuclear-grade software discipline on a first-of-a-kind reactor program. We expect engineers at this level to develop toward independent ownership of controls software scope within their first few years.

• ◆Develop and modify PLC and DCS application code on platforms such as Rockwell ControlLogix/CompactLogix, Siemens S7/TIA Portal, or equivalent, using IEC 61131-3 languages, working within established coding standards and template libraries and with structured code review by senior engineers.
• ◆Build and maintain SCADA application content on platforms such as Ignition, FactoryTalk, AVEVA, or WinCC — tag databases, user-defined types, display instances, and scripting — from established templates and standards.
• ◆Develop HMI displays at the panel and supervisory levels in accordance with the team's ISA-101/HPHMI style guide, including navigation, faceplates, and situational awareness graphics, with displays reviewed before release.
• ◆Implement ISA-88 batch phase logic and equipment module code within the established batch architecture, under the direction of senior engineers; support recipe configuration and batch testing.
• ◆Configure alarm setpoints, priorities, deadbands, and shelving in accordance with the approved alarm philosophy and rationalization outputs; run alarm performance KPI reports.
• ◆Support safety logic work under IEC 61511 by executing functional test procedures, documenting test results, and assisting with safety application code under direct senior engineer supervision; safety logic authorship and approval remain with senior engineers.
• ◆Configure historian tags, compression and exception settings, and asset framework elements within the established model; build process data dashboards and operational reports.
• ◆Configure and troubleshoot industrial communication interfaces including OPC-UA, EtherNet/IP, and Modbus TCP/RTU under guidance — server and client endpoints, tag mapping, and SCADA-to-PLC connections.
• ◆Write SQL queries and Python scripts for data processing, report generation, and control system test automation.
• ◆Apply the team's software configuration management practice: version control, change control, structured code review participation, and controller and SCADA application backup and restore.
• ◆Execute software FAT, SAT, and commissioning test procedures; support loop checks and end-to-end testing with I&C Hardware engineers; document results and maintain tag lists, alarm databases, and as-built software records.
• ◆Troubleshoot control system software faults including communication failures, logic defects, sequence stalls, and historian data gaps, escalating appropriately and documenting findings and corrective actions.
• ◆Support coordination with I&C Hardware Engineers on I/O assignment, tag naming, signal scaling, and loop commissioning.
• ◆Maintain disciplined engineering records consistent with nuclear quality requirements, ensuring traceability of design decisions, software changes, and test results.
• ◆Actively develop technical competence through structured learning, commissioning time, and progressively larger assignments, in line with the team's engineer development expectations.

Basic
